It was realized that the swelling rate coefficients increases significantly with extractive free chestnut wood-water systems resulting the initiation of the swelling process displaced towards shorter times, had lowering activation energies (Ea). The Ea of unextracted and extracted free chestnut was found to be 38.4 and 19.5 kj.mol-1, respectively. The measured maximum water absorption for unextracted samples was ranged from 141.8 % at 23 °C to 161.0 % at 100 °C However, at similar temperature level, the further increased water absorption was realized for extracted samples. It ranged from 147.7 % at 23 °C to 179.1 % at 100 °C. These features could be mainly attributed to modify cell wall chemical components resulting in a greater ease of diffusion and increase potential sites for water molecules.
